TYPICAL APPLICATION
LOW POWER, PIEZOELECTRIC POSITIONING
Piezo positioning may be applied to the focusing of segment-
ed mirror systems. The composite mirror may be composed
of hundreds of elements, each requiring focusing under com-
puter control. In such complex systems the PA90 reduces
the costs of power supplies and cooling with its advantages
of low cost and low quiescent power consumption while in-
creasing circuit density with the SIP package.
